If you're that concerned about losing 2 days and consider this critical path, then use something other than Grade 8 for the purposes of marrying everything else. You can swap in the Grade 8 stuff when McMaster opens up on Monday.

That way, you can mock everything up, marry the trans and motor, torque it all down except the motor mount thru bolts and just replace those before putting the powertrain back in the car...


...or just wait 2 days and enjoy the weekend :shrug:

If i could find something other than grade 8 that size i would, longest bolts lowes had by me were about 2" shorter than the ones i got. I have a home depot on my way home from work so i will stop there.

Might get killed for this but just thinking outside the box...HD has threaded rod, cut it to length... if your just looking for something to stick in there until you get bolts. Wouldn't leave it in there but it will get the job done for now.

Only ideas that are stupid are ones that won't work. This sounds like it would work fine for mock up

Didn't have the right size bolts m, so I went with the method above. Motor is fitted to the K currently, after dinner will mate the trans if I don't eat myself to death

You DO NOT NEED grade 8 bolts for that, grade 3 is fine, or even 5.

Even with solid motor mounts? You don't think it'll bend em?

The higher the grade the higher the tensile so more chance a grade 8 will shear off right?

Where's the engineer at when you need him??

I sure as hell wouldn't fly with threaded rod there, though. Threaded rod is the epitome of something loaded with stress risers and is usually garbage grade unless otherwise noted, then it's usually $$.

It's not permanent, it was just to get it in place. Tmmr I should have time to run to fastenal and grab some final hardware

I figured you would, I was referring to the 'any bolt will do' from Polar Bear.

I thought the idea here is to run a stronger bolt that you could torque down harder to avoid the risk of it rattling loose over time?

People automatically think grade 8 is "better", but you don't usually need that for most applications. In some places you actually want the softer bolt

That's not what I said at all. Actually a pin would probably be better because it wouldn't have any stress risers since the through bolt in all the engine mounts that I have seen, have some of the thread in the shear point in the mount.

In this application, stretch should be stretch, but I am not an engineer. If you're worried about the fastener backing off from vibration you need some sort of interference to prevent it, no amount of stretch is going to stop that in a high vibration environment. Watch to see how much a fastener will spin when it is under high vibration

I worked 8-5 Mondays, so fortunately last night i checked fastenal's hours and saw they open 7-5, so i left for work a few mins early and stopped in. Grabbed a pack of Grade 8s and some washers due to the stock bolts having a fanged head.

Final bolt down this evening !

Then I misunderstood. I thought you were implying that the threaded rod would be OK.

One benefit of higher quality fasteners is the threads are usually 'rolled' and not cut. Leads to a stronger fastener.

Cut vs rolled is solved with proper heat treating after machining operations.

So, is this car done yet?

few more odds and ends to complete. Past few days have been kinda hectic and car has been put on the back burner since friday.

Today im gunna throw the trans dipstick on, torque the balancer, and prob throw the harness on.

It makes sense to throw the O2 sensors in the collectors now right?

That will do...that will do.

Chain fall yessssssss

I'd wait on o2's, they are plenty accessible after.

Still trying to get you some welding lead :-?

No worries, i caved and ordered cable.

#SwipeLikeBLS

Wheels are on.

Today I also realized I don't have a trans dipstick lmao but I should be able to throw that in after the motor is in the car.

Harness goes on motor tmmr

Wheres the Opti? :shrug:

I have a spare, I'll add it to your parts pile.
